How Infant Positioning Impacts Hip Motion And The Associated Implications For Babies With Hip Dysplasia, Lauren Buchele

Biomedical Engineering Undergraduate Honors Theses

Developmental dysplasia of the hip (DDH) refers to a group of disorders, ranging from slight instability (Grades 1-3) to a severe dislocation (Grade 4) of the femoral head from the acetabulum [1]. In order to treat DDH in infants, a reduction procedure and the use of a lower body harness to secure the hip joint as the bones and ligaments re-form properly is typically prescribed. The Pavlik Harness is currently the “gold-standard” orthopedic device used to place hips in proper positioning. However, little research has been reported on the biomechanical affects during use of these device types.

Although the Pavlik …

Development And Exploration Of A Z-Shaped Foot And Ankle Internal Fixation Plate, Rhaz Shaghaghi Paul, Ian Hames, Sean Rich

This paper will detail the design process of developing a Z-shaped foot and ankle internal fixation plating system. Group 6: Plates for the Sole was made up of 5 team members, who worked together to accommodate their client’s request to complete a biomechanical analysis of a Z-Plate design and a construct a prototype. The Z-Plate’s purpose is to provide podiatrists with a new solution that can fit nicely on the small, irregular bones of the foot, while also remaining strong enough to withstand the forces and torques of the foot.
